PASSENGER-CAR EQUIPMENT.

Application filed January 15, 1923. Serial No. 612,796.

The invention consists essentially of the novel features pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to aflord a convenience to passengers in railway trains, so that it will be quite unnecessary to lock lavatory compartments while the train is standing or travelling within the limits of cities and subways and other places where it is desirable to keep the road bed free from waste matter; to insure reliable operation of the parts notwithstanding climatic conditions; to avoid disagreeable odors returning to the car compartment, and generally to provide in the construction of railways a simple, durable and effective container for the purposes aforesaid readily operable by the porter and easily maintained in a sweet condition.

hopper 1 converges to theexit opening 2 at the bottom end and is formed with the upper flange 3, having the flat feet 4 on the under side adapted to be'machined to agree in fitting with the thickness of the upper flooring, said hopper 1 also having the intermediate flange 5 on which the locking ring, 6 is mounted, said locking ring having the flange '7 internally threaded.

The bowl 1 is'made with theoverflow passage 8 at one side which is protected at the entrance by the shelf or wash guard 9. The wash guard or shelf 9 opens in the upturned flange 10, this opening 11 forming an outlet through which the water flows, when it rises above the shelf, otherwise the latter acts as a guard against the wash or slopping of the water within the bowl due to the movement of the car.

The cover 12 is fastened on to the bowl 1 by'the screws 13 through the margin 14 into the feet 4 and has the opening 15 into which the bowl of the car closet fits. The strainer lug 16 from the cover 12 projects downwardly in front of the slot 11 to avoid the clogging up of the overflow passage and the consequent freezing of the overflow Water.

The vent pipe 17 is in vertical alignment with the overflow pipe 19 consequently there is an uninterrupted passage from the under side of the car 18 through the interior and the roof, the deodorizer 20 being supported by the bracket 21 intermediately of the height of said vent pipe.

The flushing channel 26 is in the form of a groove 22, in the boss 23 from the underside of the cover 12 and therearound, covered in by the grooved ring 24 secured through the flange 25 to said boss, said ring being spaced from said boss to form the outlet 27 directed on all sides to the wall of the bowl. The inlet 28 to the channel 26 is made through the cover and is connected by a pipe 29 to a valve 30.

The fourway valve 30 is screwed to the floor through the base 31 and is in the form of a cross and is of conventional type having the four ports 32, 34, 35 and 36 and the central chamber 33. The valve stem boss 37 is on the side opposite the threaded plug open purposes.

ing 38 in the other side. The valve seat 39 surrounds the port 40 at the entrance to the passage l1 connected to the flushing pipe 29.

The valve 42 closes the port 40 and is secured to the stem 43 slidably mounted in the screw plug l4; screwed into boss 37 which is pierced and threaded accordingly for stem and plug. The guide plug 45 is screwed into the plug opening 138 and has the stem hole 46 for the inner end of the stem l3 and forms a stop for thespring l7 encircling the stem thus keeping the valve L2 to its seat 39 except during the flushing operations.

The press button l8 forms the head of the stem43 and is rounded off on the outer surface 49 to facilitate the operation thereof.

The port 3% of ihe valve 30 is joined through the coupling .50 to the pipe 29 and the port 32 is shown as connected to the pipe .51 from the tank beneath the flooring and illustrated by parallel lines as being in Figure 1 behind the vertical shaft .56. In Figure 6 one port is shown as closed by the screw plug 52 and another by the screw cap .53, thus showing the possible variations in the ports according to conditions of installation.

The floor plate 55 is secured to the floor at a suitable distance from the four way valve 30 and forms a bearing for the vertical operating shaft 56, on which is fixedly mounted the crank lever 57 having the operating handle 58 at one end of its lever arm 59 and the balance weight .60 at the other end beyond the point.

The central 'jlug 61 projects from the handle end of the ,arm 59 and to this the dog 62 is pivotally secured through the lugs 63 and 64;.

The dog 62 is formed with .a curved cam face 65 adapted to engage the press button 48 so that when the crank lever is operated in one direction the stem 43 is pushed inwardly and opens the valve 42 for flushing The steps 66 and 67 are provide-d for limiting the strokes of the operating handle 58. The return stroke does not affect the position of the valve stem l3 as the dog 62 is formed with a tapered end and long bevelled surface v68, which enables "it to ride over the press button i8 on account of its pivotal mounting, therefore the flushing of the bowl only occurs during the opening stroke, when the outlet from the bowl is wide open as explained more fully hereinafter.

The shaft 56 is jounnalled at its lower end in the bracket hanger 69 secured to the under side of the car body and the rack 70 is also slidahly supported from said bracket.

The rack 'f? 0 is formed as an internal gear having the teeth 71 along one side of the longitudinal pinion passage 72- which is parallel to the roller guide slot 73, the latter being open on the inside to the pinion passage 72, so that the guide roller 74- journalled on the spindle T5 secured in the bracket 69 may engage the guide discs 76 and 77 mounted. on the shaft 56 and flanking the pinion 7:8, which coacts with the teeth 71 in reciprocating the rack '70.

The roller 74 is spool shaped, that is to say recessed centrally at 79 leaving the friction disc surfaces 80 and 81 at the ends to engage the discs 76 and 77 and so maintain a good operative \coaction between the pinion and rack teeth and at the same time eliminate any rattling.

The shaft 82 is secured in the socket forming the projecting end of the rack 70 and is held by the cotter pin 84:. though any suitable form of coupling may be used.

The shaft 82 at its other end is secured to the slide valve 85 between the lugs 86 and 87 by the cotter pin 88.

The slide valve 85 is hollow forming the hot air chamber 89 open at the shaft end and closed at the other end and having through the sides the circulation vents 90. The bottom of the slide is made with the longitudinally bevelled runners 91 forming wedge surfaces in closing operations. The top of the slide is slightly raised above the edge portions and slopes to an inclined drain 93 discharging over side of the top, thereby keeping the valve surface free of liquid accumulations.

The slide valve 85 is mounted on the ledges 94-. and .95 at the sides of the valve chamber 96, said'ledges forming slide ways for the valves, these ledges being depressed at '97 to form pockets for the wedge blocks 98 seated .on the wedge bases 99, both wedge blocks and bases being held in place by the lugs 100 forming continuations of the chair.- her walls, said wedge bases 99 being adjusted by the set screws 11?. The runners 91 slide on the ledges 94- and 95 and therefore engage the wedge blocks 98 slightly above the ledge surfaces at one end, therefore the slide valve 85 is wedged tightly to its seat 101 formedby the copper packing ring 1052 encircling the lower end of the bowl 1 in the recess 103.

The steam radiator 10% is preferably integral with the casing of the valve chamber 96 and extends above "the top wall, and it may "here be mentioned that in the outer wall of the chamber 96 the cap 105 is secured by the bolt 106, and it is through this cap 105 that the shaft 82 extends to the slide.

The steam radiator 10st is formed of a casing superposed on the valve chamber 96 and divided by the longitudinal partition 107 meeting the circular partition 108 surrounding the bottom of the bowl, thereby forming an inlet passage 109 connected by the pipe 110 to the train line steam pipe and forming an outlet passage 11]. connected to the the end towards each all) exhaust pipe 112 and to a vapor regulator 113, the said inlet passage communicating with the said outlet passage through the circular passage 11 i encircling the bowl, said circular passage 114 having its walls slightly elevated to form the threaded projecting portion 115 of the casing adapted to be screwed into the locking ring 6 supported by the flange 5 aroundthe bowl 1.

The wool fibre insulation 116 is securely packed around the bowl 1 over the steam radiator 104 to maintain the parts in a comfortable condition.

In the operation of this device the waste matter from the bowl in the car con1partment is let into the under car waste bowl with the accompanying flushing water and remains therein while the train is at a station or within the limits of a city or other prohibitive place, and during that period the noxious odors float upwardly through the vent pipe where they becom disinfected and harmless through treatment with the deodorizer in said pipe.

During the travel of the train in country part-s away from inhabited localities, the crank lever is operated by means of its handle and this draws the rack along, and through the shaft connection removes the slide valve from the outlet opening at the bottom of the bowl and coincidently the dog at the end of the lever engages and presses the button of the water valve stem, which opens the water supply, and as this is under pressure the water flows through the four way valve body into the pipe connecting said body with the flushing channel. The said flushing channel surrounds the upper end of the bowl where the flushing water is expelled through the outlet on to the inside surface of the bowl. The crank lever is then turned to perform its return stroke, and the dog rides over the press button and the slide valve returns to its closed position being wedged tightly to its seat by the contact of the runners and wedge blocks. The slide valve is kept constantly warm by the steam radiator, which provides hot air within it as well as around all parts exposed within the valve chamber. The bowl is kept warm at the outlet, so it is quite impossible for ice to collect and choke up the outlet and surroundings and prevent the operation and the functioning of the slide valve.
